What is DDR3?

DDR3, or Double Data Rate 3, is a type of computer memory used to store data temporarily for faster access by the processor. DDR3 was released in 2007 and is a successor to DDR2. DDR3 RAM (random-access memory) sticks for a desktop computer have 240 pins. For a laptop computer, DDR3 RAM sticks have 204 pins.

These memory chips can only be installed on a motherboard that supports DDR3 memory and are not backward compatible with DDR2 memory slots.
Can I use any DDR3 RAM in my PC?

Before buying a computer memory update, it's important to understand the capabilities of your system. Understanding the differences between DDR3, DDR4 and DDR5 will help you pick a product that's right for you and your computer. For example, investing in a memory upgrade with a clock speed higher than what your PC can support, will not have the desired speed and efficiency benefits you're looking for.
